IMPROVEMENT IN FIRE-EXTINGUISHING WATER-PIPE ATTACHMENTS T0 BUILDINGS.

vSpecification forming part of Letters Patent No. 149,669, dated April 14, 18,74; application filed March 28, 187 4.

To all 'whom it 'may concern:

Be it known that I, THOMAS MILLER, of Jersey City, Hudson county, New Jersey, have invented a new and useful Improvement in Fire-Extinguishing VVater-PipeV Attachments for Buildings, of which the following is a specification My invention relates to utiliing the firecxtinguishing water-pipe attachments used to conduct the waterto the upper stories and the roofs, for nre-ladders also; and it consists of, preferably, two pipes side by side, or one separated into two branches above the lower story, with rungs for a laddencrossing from one to the other and connected to them, said rungs being made of tubes, for allowing the water to circulate through them to keep them cool when exposed to fire in the building, and thus make the ladder available when it would notalways be with solid rungs, which heat when solid, so as to render the ladder useless.

Figure 1 is a side elevation of a fire-extinguishin g fwater-pipe attachment and ladder, illustrating my invention it also shows a front elevation of a part of a house in dotted lines. Fig. 2 is a side elevation of the water- Vpipe and ladder attachments, with a part broken out.

Similar letters of reference indicate correspondin g parts.

A- represents two pipes, side by side, a short distance apart, extending up the side of the building, with pipe-connections or nozzles B for discharging water into the house at the different floors and onto the' roof. C represents hollow or tubular rungs of metal connected to the pipes to form a ladder for the escape of persons in the house when egress by the usual way is cut oft' by the re. These pipes A are, in this case, in two branches of a single pipe, D, at or below the second oor of the building, having a pipeconnection, E, for attaching the hose of the engine, and extending down `to, and connecting with, the main of a water-supply apparatus, if required, with cocks G and H, for shutting off and letting on the one or the other. T-hree or more pipes may be used, making a double or triple lad-- der, if preferred, but probably two will be most desirable. I also propose to make the rungs of a single pipe-ladder hollow, for pro-v tecting them Jfrom heat, in the same manner.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The rungs employed, in combination with the fire-extinguishing water-pipe attachment to buildings for converting it into a tire-escape, made hollow, and connected with the pipe or pipes in such manner that the water will circulate in and protect them from heat, whether one, two, or more stand-pipes are used, substantially as specified.

THOMAS MILLER.
